Cordierite Ceramic
Wuxi Special ceramics offer cordierite materials with dense and porous strutures,all of which are distinguished by
an outstanding thermal shock resistance,while at the same time
having high heat resistance and electrical insulation strength.
Cordierite ceramics are grouped in to C410,C511,C520 and C530
In accordance with C410,C511,C520 and C530 in compliance with
IEC672 are ceramic materials on the basis of cordierite,a magnesium
aluminium silicate mineral with extremely low thermal expansion.In
addition,they contain additives of mullite,corundum and silicon
carbide.
Why choose Cordierite materials
A. outstanding thermal shock resistance
B. high degree of electrical insulation strength
C. corrrosion resistance
D. high heat resistance(C530 up to 1300℃,specialities up to 1600℃)
E. comparatively lower production costs
Ceramic bobbin for water heater
Ceramic bobbin heater is made of porous cordierite(C520)ceramic heating element with wire.
It heat liquids or semi-solid materials such as
water,oil,wax,fats,and bitumen.These heaters are mainly used for
direct heating of air and indirect heating of liquids and gases
where the element is fitted into a pocket in the process tank or
system so that the element may be replaced without draining down
the system or vessel.
Why choose Wuxi Special ceramic?
A. Dry pressed molding with high mechanical strength
B. Lower production cost
C. Fast delivery with large quantity
